sdk: Make Packet::meta private, use accessor functions (#29092)

Michael Vines 3f4731b37f Standardize thread names 
Tenets:
1. Limit thread names to 15 characters
2. Prefix all Solana-controlled threads with "sol"
3. Use Camel case. It's more character dense than Snake or Kebab case

removes raw indexing into packet data (#25554) 
Packets are at the boundary of the system where, vast majority of the
time, they are received from an untrusted source. Raw indexing into the
data buffer can open attack vectors if the offsets are invalid.
Validating offsets beforehand is verbose and error prone.

The commit updates Packet::data() api to take a SliceIndex and always to
return an Option. The call-sites are so forced to explicitly handle the
case where the offsets are invalid.

behzad nouri 81231a89b9 adds support for different variants of ShredCode and ShredData 
The commit implements two new types:
    pub enum ShredCode {
        Legacy(legacy::ShredCode),
    }
    pub enum ShredData {
        Legacy(legacy::ShredData),
    }

Following commits will extend these types by adding merkle variants:
    pub enum ShredCode {
        Legacy(legacy::ShredCode),
        Merkle(merkle::ShredCode),
    }
    pub enum ShredData {
        Legacy(legacy::ShredData),
        Merkle(merkle::ShredData),
    }

removes shred wire layout specs from sigverify (#25520) 
sigverify_shreds relies on wire layout specs of shreds:
https://github.com/solana-labs/solana/blob/0376ab41a/ledger/src/sigverify_shreds.rs#L39-L46
https://github.com/solana-labs/solana/blob/0376ab41a/ledger/src/sigverify_shreds.rs#L298-L305

In preparation of
https://github.com/solana-labs/solana/pull/25237
which adds a new shred variant with different layout and signed message,
this commit removes shred layout specification from sigverify and
instead encapsulate that in shred module.

limits read access into Packet data to Packet.meta.size (#25484) 
Bytes past Packet.meta.size are not valid to read from.

The commit makes the buffer field private and instead provides two
methods:
* Packet::data() which returns an immutable reference to the underlying
  buffer up to Packet.meta.size. The rest of the buffer is not valid to
  read from.
* Packet::buffer_mut() which returns a mutable reference to the entirety
  of the underlying buffer to write into. The caller is responsible to
  update Packet.meta.size after writing to the buffer.

Make PacketBatch packets vector non-public (#25413) 
Upcoming changes to PacketBatch to support variable sized packets will
modify the internals of PacketBatch. So, this change removes usage of
the internal packet struct and instead uses accessors (which are
currently just wrappers of Vector functions but will change down the
road).

enforces that LAST_SHRED_IN_SLOT is also DATA_COMPLETE_SHRED (#24892) 
A data shred cannot be LAST_SHRED_IN_SLOT if not also DATA_COMPLETE_SHRED.
So LAST_SHRED_IN_SLOT should also imply DATA_COMPLETE_SHRED:
https://github.com/solana-labs/solana/blob/74b586ae7/ledger/src/shredder.rs#L116-L117
https://github.com/solana-labs/solana/blob/74b586ae7/core/src/broadcast_stage/standard_broadcast_run.rs#L80-L81

However current shred constructs allow specifying a shred which is
LAST_SHRED_IN_SLOT but not DATA_COMPLETE_SHRED:
https://github.com/solana-labs/solana/blob/74b586ae7/ledger/src/shred.rs#L117-L118
https://github.com/solana-labs/solana/blob/74b586ae7/ledger/src/shred.rs#L272-L273

The commit updates ShredFlags so that if a shred is not
DATA_COMPLETE_SHRED it cannot be LAST_SHRED_IN_SLOT either.

replaces Shred::new_empty_coding with Shred::new_from_parity_shard (#24749) 
Removing implementation details of shreds and payload offsets from
shredder, so that shredder does not need to mutate payload:
https://github.com/solana-labs/solana/blob/71ad12128/ledger/src/shred.rs#L968-L977

Also, Shred::new_from_data can simply obtain a slice as opposed to
Option<&[u8]>:
